Subject: [PATCH] configure: Remove old *-config-devices.mak.d files when
 running configure

When running "make" in a build directory from the pre-Kconfig merge time,
the build process currently fails with:

make: *** No rule to make target `.../default-configs/pci.mak',
needed by `aarch64-softmmu/config-devices.mak'. Stop.

To make sure that this problem at least goes away when the user runs
"configure" (or "sh config.status") again, we have to make sure that
we re-generate the .mak.d files. Thus remove the old stale files
while running the configure script.

Backports commit 9c79024225af6b3ae04ea2dd94a5e5c4132a9e65 from qemu
